Abstract: The influence of dynamic optical interference on the reliability of decision-making by high-speed optoelectronic devices for detecting the source of ignition at an early stage in an explosive dust and gas atmosphere has not been adequately studied in the literature. Therefore, earlier for their study, experimental installations and techniques were developed to study the dynamic characteristics of typical optical interference in the form of dynamic spectral characteristics of the radiation of incandescent lamps. As a result of the work, a laboratory study of the dynamic characteristics of optical interference sources was carried out. Dynamic characteristics of sources of optical noise by a method with a spreading on a wavelength are received. The maximum spectral radiation flux in the steady-state operating mode for a direct current incandescent lamp is at a wavelength of 1.16 μm, and for an incandescent lamp of alternating current at a wavelength of 1.18 μm. The temperature of the filament body varies in the range from 1390 K to 2500 K for an incandescent lamp operating at a constant current and in the range from 1390 K to 2450 K for an incandescent lamp operating on alternating current. Dynamic characteristics of sources of optical noise are obtained by a method with a scanning according to the supply current. The maximum spectral flux of the incandescent lamp in the steady-state operating mode is at a wavelength of 1.2 μm. Using the Wien displacement law, dynamic spectral characteristics for an incandescent lamp in the range from 1670 K to 2415 K were obtained. As a result of laboratory research, an installation and a method with a wavelength sweep were chosen as the installation and method for studying the dynamic characteristics of optical interference sources in the form of radiation from incandescent lamps.
